Electric ammonia dedicated switch valve
be commonly called: Electric ammonia special on-off valve Electric liquid ammonia special on-off valve Electric liquid ammonia special shut-off valve Electric ammonia special shut-off valve
Model: YL-AOX-M/941
Overview of ammonia special on-off valve:
Electric ammonia dedicated switch valve adopts explosion-proof electric actuator, which is suitable for combustible gas/liquid remote control occasions. With 380V/220V/110V AC power supply as the driving power and 4-20mA current signal or 0-10V DC voltage signal as the control signal, the electric ammonia dedicated switch valve can make the valve move to the desired position to realize the control of pressure, flow, temperature Functions of parameters such as liquid level.
The electric ammonia special on-off valve adopts two-way bubble sealing, with good sealing performance. The valve seat is made of Japanese Daikin polytetrafluoroethylene material (PTFE or RPTFE), which has pressure relief grooves on the outer diameter to reduce the fluid pressure passing through the inlet end. As the ball is floating, under the action of medium pressure, the ball can produce a certain displacement towards the outlet end and press on the sealing surface of the outlet end. The sealing force increases with the increase of medium pressure, and has a good preload to ensure low-pressure sealing and vacuum sealing. The valve stem is designed with anti blow out and anti-static structure, which can lead the static electricity carried by the ball and valve body to the ground.

The electric ammonia special on-off valve is a fully electronic electric actuator. Its shell is made of hard aluminum alloy, which has been anodized and coated with polyester powder. Its corrosion resistance is strong, and its protection level is IP67. The motor is an integrated structure, with small size, large torque, small inertia force, insulation level of F, and built-in overheat protection switch, which can prevent damage to the motor. It has the functions of internal servo operation, position feedback of opening signal, position indication, manual operation, etc. It has strong functions, reliable performance, and simple wiring. Through the input of current signal or voltage signal, it can change the rotation angle of the ball core (0-90 ° any angle) to achieve fast switching action. The special ammonia on-off valve is interlocked with the electric box control cabinet, fire protection system, combustible gas detection alarm, SIS safety interlocking system/DCS/ICS control center (plant management information system/MIS system) to realize the remote automatic control of enterprise production.
